My Garden System is running ok. I can control manually all the system but now I wanted to control virtual pin (V50) which on/off all the system in case of rain in my area. For this reason I was checking all the messages in this and another forums and this is what I found:

Using these sentences I’m able to ON or OFF the Blynk Virtual PIN (V50) and I see the change in the iOS App (I change AUTH_TOKEN by my token):

You should always use the IP address of the Blynk server where your project lives, rather than blynk-cloud.com because of GeoDNS issues when using the API.

Both options work from your home PC, because the blynk-cloud URL resolves to the same IP address from your home location. The IFTTT servers may be on the other side of the world, and blynk-cloud.com will resolve to a differentserver, and as your project cant be found on that server iot will return an “invalid token” error.

Hi Pete, thks for your reply. I did and the service is working at least to generate a next day forecast at a time and send it to my email. What I did now is to generate 2 IFTTT recipe to send notifications instead of changed Virtual PIN, one of them if weather changes to CLEAR and another one if it changes to RAIN.

I keep waiting if it works with notifications and then I will try again changing PINS on my Arduino.

Finally WU services is not working anymore. Then in order to check which sentence works for my watering system, I linked my netatmo heating system and it worked. When I changed temperature to manual I setup to OFF V50 with
